Design and Implementation of Multifunctional Virtual Oscilloscope

Qin Gao

Abstract

This paper,taking the double-channel virtual oscilloscope as an example,gives the design process of virtual instrument based on NI USB-6009 board and LabVIEW software and describes in detail how to realize the virtual oscilloscope form the design of system and the implementation of hardware and software.The virtual oscilloscope is of these functions including waveform display,parameter measurement,filter,spectral analysis,data storage and playback.As compared with the conventional oscilloscope,this system could simplify the structure,improve the test performance,and realize the automatic test.
